Assume that 40% of a country's population has had Covid and that 55% of the country's population has been vaccinated. There is some overlap between the two groups, and 25% of the country's population has both had Covid and has also been vaccinated. Either having Covid or being vaccinated gives some protection against getting Covid. Based on these assumptions, if you choose a resident of this country at random what is the probability that the person has either had Covid or has been vaccinated and therefore has some protection against Covid?
The probability that the person has either had Covid or has been vaccinated and therefore has some protection against Covid is 45%
Data obtained from the questionFrom the question given, the following data were obtained:
40% of a country's population has had Covid55% of the country's population has been vaccinated25% of the country's population has both had Covid and has also been vaccinatedHow to determine the required probabilityThe probability that the person has either had Covid or has been vaccinated and therefore has some protection against Covid can be obtained as follows:
The percentage of person that had Covid and not vaccinated
= 40% - 25%
= 15%
The percentage of person that has been vaccinated and never had Covid
= 55% - 25%
= 30%
The probability that the person has either had Covid or has been vaccinated
= 15% + 30%
= 45%

What does the compound annual rate signify?The compound annual rate is the equivalent rate of interest at which the present value of money grows to attain a future value.
At a 4.9% compound annual rate, Anders' salary has been growing by adding the growth amount to the initial salary and compounding both the principal and subsequent interest amounts until 12 years.

X- -3,-2,-1,0
f(x)-6,0,-2,0
An equation of the quadratic function in standard form is equal to -2x² - 7x - 6 = 0.
What is a quadratic function?A quadratic function can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c = 0
y = f(x) = ax² + bx + c
Next, we would formulate a system of equations from the data contained in the table above:
-6 = a(-3)² + b(-3) + c ⇒ -6 = 9a - 3b + c .......equation 1.
0 = a(-2)² + b(-2) + c ⇒ 0 = 4a - 2b + c .......equation 2.
-2 = a(-1)² + b(-1) + c ⇒ -2 = a - b + c .......equation 3.
From eqn. 2, we have:
c = -4a + 2b .....equation 4.
Substituting eqn. 4 into eqn. 1 and 3, we have:
-2 = a - b - 4a + 2b ⇒ -2 = -3a + b
-6 = 9a - 3b - 4a + 2b ⇒ -6 = 5a - b
By using the elimination method, we have:
-8 = 2a
a = -4
For the value of b, we have:
-2 = -3a + b
b = -2 + 3a
b = -2 + 3(-4)
b = -2 - 12
b = -14
For the value of c, we have:
c = -4a + 2b
c = -4(-4) + 2(-14)
c = 16 - 28
c = -12.
Substituting the values of a, b and c into the standard form of a quadratic equation:
ax² + bx + c = 0
-4x² - 14x - 12 = 0

Equation: h(t) = 96t - 16t²
This equation will form a parabolaThe zeros of the parabola will indicate the start time and height (0,0) and the end time and height (x, 0)The maximum point will be the maximum height the ball will reachThe maximum point will be the halfway point between the two zerosStep-by-Steph(t) = 96t - 16[tex]t^{2}[/tex]
Find the zeros of the given equation:
Factor out the greatest common factor (GCF)
h(t) = 8t (12 - 2t)
The two factors are:
0 = 8t
0 = 12 - 2t
For both factors, solve for t
8t = 0
8t/8 = 0/8
t = 0
12 - 2t = 0
-2t = -12
t = 6
Now we have the x-values (t) of our zeros:
t = 0
(0, 0)
t = 6
(6, 0)
The ball will land on the ground at 6 seconds
Recall that the maximum point of the graph is halfway between the two zeros:
6 + 0 = 6
6 ÷ 2 = 3
The ball will reach its maximum height in 3 seconds
To find this height, substitute t for 3 in the given equation, and solve for h:
t = 3
h(3) = 96(3) - 16(3)²
= 288 - 16(9)
= 288 - 144
= 144
The maximum height the ball will reach is 144 feet
***Refer to the graph below to check your answer:
=======================================================
Explanation:
I'll use x in place of t
And use y in place of h(t)
The equation we have is y = 96x - 16x^2
This rearranges to y = -16x^2 + 96x
Compare this to y = ax^2+bx+c to find that
a = -16b = 96c = 0The x coordinate of the vertex is
h = -b/(2a)
h = -96/(2*(-16))
h = 3
Then plug this into the equation to find the value of y
y = -16x^2 + 96x
y = -16(3)^2 + 96(3)
y = 144
The y coordinate of the vertex is k = 144
The vertex is located at (h,k) = (3, 144) to represent the highest point of the parabola.
The max height of 144 feet occurs when the ball is in the air for 3 seconds.

What is the Domain and Range of the Function?The domain of a function is the set of all possible input values that make a function possible. Meanwhile the range of a function is the set of all possible output values that make a function possible.
Now, when dealing with an inequality graph, it is pertinent to note that a shaded dot implies less than or equal to (≤) or greater than or equal to (≥) while unshaded means less than or greater than.
Now. the range of the graph is closed from y = -6 to y = 6. Thus, the range is; {y| -6 ≤ y ≤ 6}
